Once Zeroed - Never Change

[ray1970]

I've been leery of the quick disconnect AR scope mounts because of the return-to-zero question. I assumed it was hollywood being hollywood. The reading I've done on the AR QD mounts indicates they return pretty close to their original zero. So, I suppose it's not as far-fetched as I had always assumed when seeing it in the movies.

That test of the mounts was pretty impressive. Even the worst one was within less than a quarter MOA. Theoretically, it would mean you would be off less than one inch with your point of impact at 400 yards. I guess if you were shooting a target the size of a golf ball at that distance it might make or break the shot but putting a round into center of mass and being off an inch at that distance is pretty inconsequential.

Exactly. One has to ask them self. What are my expectations of the tools i'm using? IMO, unless you're sitting on a perch, waiting for the GO signal, to remove a threat. The minor shift, if at all , is minimal at it's worst. My scopes have zero POI shift when removed, if needed. But if one were to vary, like an older optic i have. 2 rounds tops to get back to zero. 1 to get there, the other to confirm.
